What is required for openings through concrete or masonry building elements in terms of pipe penetrations?

For openings through concrete or masonry building elements regarding pipe penetrations, the requirement typically involves the use of sleeves. When pipes pass through these durable materials, sleeves serve several important functions. They provide a protective barrier for the piping, reducing the risk of damage from the surrounding concrete or masonry. Additionally, sleeves help to maintain the integrity of the building element by allowing for thermal expansion and contraction of the pipe without compromising structural safety.

Using sleeves also facilitates easier installation, maintenance, and potential future modifications to the piping system. It is common for codes to require sleeves in order to ensure compliance with safety and performance standards, which are essential in preventing any potential issues like cracking, leaking, or structural failures due to improper piping installations.
